I’ve got a Raspberry Pi 3 and I’ve installed Arduino 1.8.10. When I hook up my Makey Makey v1.2 to a USB port with left-right and up-down wired for programming, it sends the string “mm v1.20ac”. So far so good.
In Arduino, I’ve installed the Sparkfun AVR board and selected Makey Makey.
The only serial port I’m seeing in Arduino, even when I launch it with sudo, is /dev/ttyAMA0, which I think is Bluetooth serial on a Raspberry Pi 3.
Am I barking up the wrong tree here? Is it already known that this combination won’t work in order to upload custom firmware?
